Find the value of x
Please help!

Answers

Answer 1

Answer:

Step-by-step explanation:

We have to use Pythagorean's Theorem twice here, first to find the length of the dotted line, which I will call h, and then again to find x. First we need to find h so we can use it to find x:

[tex](2\sqrt{5})^2=4^2+h^2[/tex] and

[tex]20=16+h^2[/tex] and

[tex]4=h^2[/tex] so

h = 2. Then again:

[tex]x^2=2^2+22^2[/tex] and

[tex]x^2=4+484[/tex] and

[tex]x^2=488[/tex] so

x = 2√122

What pair of angles must have the same measure?I'll give brainliest if its correct.

Answers

Answer:

[tex]\text{(C) }\angle 2\text{ and }\angle 7[/tex]

Step-by-step explanation:

Angle 2 corresponds with angle 6 and since all corresponding angles are equal, [tex]\angle 2=\angle 6[/tex]. Angle 6 and angle 7 happen to be vertical angles (opposite side of an intersection of two lines). Since all vertical angles are also equal, [tex]\angle 6=\angle 7[/tex] and by substitution, we have: [tex]\implies \boxed{\text{(C) }\angle 2\text{ and }\angle 7}[/tex]

Angle 2 and 7 is the answer!!

Answer:

Tan <A = 4/3

Cos <A = 3/5

Sin <A = 4/5

Step-by-step explanation:

From the diagram given

Hypotenuse AB = 10

Adjacent = 6

Opposite = 8 (side facingc<A)

According to SOH CAH TOA

Tan <A = Opposite/adjacent

Tan <A = BC/AC

Tan <A = 8/6

Tan <A = 4/3

For Cos <A;

Cos <A = adj/hyp

Cos <A = 6/10

Cos <A = 3/5

For sin<A:

Sin <A = opp/hyp

Sin <A = 8/10

Sin <A = 4/5

Answers

Answer:

Step-by-step explanation:

To overestimate the area would mean that you completely enclose the circle in squares; an 8 x 8 square to b exact. The area of a square with sides measuring 8 is 64. The overestimation is 64.

To underestimate the area would mean that you only count the squares that are completely inside the circle. That would be a 6 x 6 square (even though the 6th squares are a tiny bit outside the circle). A square with sides of 6 has an area of 36. The underestimation is 36.

Cameron sponsored a fundraiser that 582 people attended. He raised 6,480. He charged $15 for balcony seats and $10 for ground seats. How many people bought balcony seats (b) and how many bought ground seats (g)?

15b + 10g = 6,480
b + g = 582

Answers

Answer:

132 people bought balcony seats and 450 people bought ground seats.

Step-by-step explanation:

We want to solve the system of equations:

[tex]\left\{ \begin{array}{ll} 15b+10g=6480 \\ b+g=582 \end{array} \right[/tex]

We can solve this by using substitution. From the second equation, we can subtract b from both sides:

[tex]g=582-b[/tex]

In the first equation, we can divide both sides by five:

[tex]3b+2g=1296[/tex]

Substitute:

[tex]3b+2(582-b)=1296[/tex]

Distribute:

[tex]3b+1164-2b=1296[/tex]

Simplify:

[tex]b+1164=1296[/tex]

Solve for b:

[tex]b=132[/tex]

Using the modified equation again, substitute:

[tex]g=582-(132)[/tex]

Evaluate:

[tex]g=450[/tex]

Therefore, 132 people bought balcony seats and 450 people bought ground seats.

The angle 1 and the side equal to 72° together equal 180. 72 + x = 180 using the subtraction property of equality we can conclude that x = 108.

Side 2 is parallel with 72° making them equal and Side 3 is parallel with 108° making them equal.

Side 1 = 108°
Side 2 = 72°
Side 3 = 108°

Side 1=108
Side 2=72

What are the coordinates of the point on the directed line segment from (−8,−6) to (-1, 8) that partitions the segment into a ratio of 5 to 2?

Answers

Answer:

(-3, 4)

Step-by-step explanation:

let the point P(x, y)

x = (5/7 × (-1+8)) + (-8)

= (5/7 × 7) -8 = 5-8 = -3

y = (5/7 × (8+6)) + (-6)

= (5/7 × 14) -6 = 10-6 = 4

so, P => (-3 , 4)

The prism shown in the above diagram is a triangular prism.The two distinctive sides that give a prism its name are its bases.So, the base of the prism should be in the shape of a triangle.The faces "b", "c", and "d" are rectangular, so they can not be the base of the prism.The faces "a" and "e" are triangular, so they are both the bases of the prism.Checking the options, we conclude that face "a" is the base of the given prism.Thus, the letter that correctly identifies the base of the prism is "a".
